Abstract (en)
[origin: WO2018175377A1] An imaging system images a sample across one or more wavelengths. A light source illuminates a sample with one or more wavelengths of light, and an image sensor detects light from the illuminated sample. A linear variable long pass filter is positioned to filter light reflected from the sample to pass to the image sensor multiple different wavelength bands having different cut-off wavelengths. Wavelengths of light on one side of the cut-off wavelength are blocked and wavelengths of light on the other side of the cut-off wavelength are passed as multiple different long pass wavelength bands for detection by the image sensor. The image sensor detects light for each of the multiple different long pass wavelength bands from the sample. Data processing circuitry converts the detected light for the multiple different long pass wavelength bands for the sample into corresponding different long pass wavelength band data sets for the sample.
